Coins-mail NPM

HTML and text email templates for COINS.

Example

Create Mail

The createMail is coins-mail’s chief export. It expects a configured Bookshelf.js model:

const knex = require('knex')({
  /* DB config ... */
});
const bookshelf = require('bookshelf')(knex);
const createMail = require('coins-mail').createMail;

const MyMailModel = bookshelf.Model.extend({
  tableName: 'my_table_name',
});

createMail(MyMailModel, options); // returns Promise

createMail returns a Promise. In the case of a single mail option, this is the result of calling save on a Bookshelf.js model. In the case of a collection of mail options, this is the result of invoking save on the Bookshelf collection.

Options:

options can be either a mail options object or a collection of these objects:

fromLabel (string): Added to the from_label column. This is typically the name of application sending the email.
recipients (string or array of strings): Single recipient email address or a collection of email addresses.
replyTo (string): Email address to use in the email’s 'reply to' field.
subject (string): Email’s subject field.
templateLocals (object): Hash to pass to getTemplate. The keys/values depend on the email template in use (see templateName).
sendTime (string, defaults to Date.now()): Time to send the email.
templateName (string, defaults to “default“): Name of email template to use.

Single email

  createMail(MyMailModel, {
    fromLabel: 'Test Application',,
    recipients: [
      'recipient-1@mrn.org',
      'recipeint-2@mrn.org',
      'recipient-3@mrn.org',
      // ...
    ],
    replyTo: 'reply-address@mrn.org',
    sendTime: Date.now() + 24 * 60 * 60 * 1000,
    subject: 'Test Subject',
    templateLocals: {
      html: {
        myHtmlTemplateVar: 'value',
      },
      text: {
        myTextTemplateVar: 'value',
      },
    },
    templateName: 'my-template',
  })
    .then(savedModel => console.log(savedModel))
    .catch(error => console.error(error));

Multiple emails

createMail(MyMailModel, [{
  fromLabel: 'Test Application 1',
  recipients: 'recipient-1@mrn.org'
  replyTo: 'reply-address@mrn.org',
  subject: 'Test Subject 1',
  templateLocals: // ...
}, {
  fromLabel: 'Test Application 2',
  recipients: 'recipient-2@mrn.org'
  replyTo: 'reply-address@mrn.org',
  subject: 'Test Subject 2',
  templateLocals: // ...
}, {
  fromLabel: 'Test Application 3',
  recipients: 'recipient-3@mrn.org'
  replyTo: 'reply-address@mrn.org',
  subject: 'Test Subject 3',
  templateLocals: // ...
}])
  .then(savedModels => {
    savedModels.forEach(savedModel => console.log(savedModel));
  })
  .catch(error => console.error(error));

Template

const getTemplate = require('coins-mail').getTemplate;

getTemplate({
  html: {
    myHtmlTemplateVar: '<h1>Hi!</h1> <p>Insert this html…</p>',
  },
  text: {
    myTextTemplateVar: 'Alternative!\n\nFor the text version…',
  },
}, (error, result) => {
  if (error) {
    console.error(error);
  } else {
    console.log('HTML:', result.html);
    console.log('Text:', result.text);
  }
});

getTemplate also returns a Promise:

getTemplate(myLocals)
  .then(result => {
    console.log('HTML:', result.html);
    console.log('Text:', result.text);
  })
  .catch(error => console.error(error));
